    Hello, I am looking for about 500 words and some references to describe these particular methods used by the IAEA to confirm the absence of undeclared nuclear activities and material at the different nuclear facilities within the nuclear fuel cycle, particularly just a focus on methods used for Isotopic (IDMS,...) and Particle (α-spectr,...). If you can add a link to a good descriptive picture, that would be great too. Let me know, thanks.

    In reference to the nuclear safeguards that are used by the IAEA in regard to alpha spectrometry and IDMs, the current technology utilizes a suitable tracer that is referred to as a spike, which is in accordance with the preferred method to mitigate issues associated with tail contribution as a result of the degrading of energy that occurs during alpha spectrum nuclear activities. By utilizing this method, IAEA monitors have the ability to eliminate the uncertainty that is present with the steps taken to prepare samples for analysis as these steps require an elaborate approach that results in chemical yields that can cause misdiagnoses. In addition to the aforementioned technology, it is possible to utilize high resolution alpha spectrometry in a method that enables the deconvolution algorithms to be used in unison with this approach to enable the IAEA to use non-isotopic tracers. By utilizing these (N-IDAS), the IAEA monitors have the ability to better and more accurately determine whether close lying x-energies are a result of radionuclide pairs that emanate from nuclear activity that is for nefarious purposes.

    In essence, the use of Alpha spectrometry has increasingly become an important tool for verifying non-nuclear states are decommissioning their nuclear reactors in accordance with the guidelines and regulations mandated by the IAEA as well as adhering to the international rules and guidelines established for waste disposal programs. This assists in ascertaining whether radioactive nuclides are still present within the environment. This approach is also effective in minimizing the time required to accurately provide data during any contamination occurrences while also enabling quicker confirmations on nuclear samples obtained from nuclear sites.

    Another important safeguard that is utilized by the IAEA entails the use of spectrometric techniques that enable the nuclear material to be assessed within analytical laboratories using tools such as thermal ionization mass spectrometry. This along with other mass spectrometry techniques are utilized by the IAEA to better provide an analysis of the nuclear material that has been acquired through the collection of environmental samples by giving precise and accurate readings that are in accordance with a more time-effective approach that reduces the likelihood of inaccuracies occurring because of nuclear molecular interferences.

    It's imperative for the individual IAEA agents to choose the most applicable safeguard for the situation on the ground, which is why it is advisable for IAEA agents to garner an understanding of each separate technique so that they can obtain a myriad of different data to assess for nuclear activity. The technologies that have been discussed enable the IAEA monitors the ability to effectively review whether there are isotopic compositions of uranium and plutonium located within the environment, soil samples, and other analyses.
